How to disperse and stabilize pigments

The copper phthalocyanine molecule has been modified by the addition of polymeric chains to give a particularly effective dispersing agent for copper phthalocyanine pigments. Alternatively, derivatives with substituted ionic groups can be used to activate the surface of a pigment and make it receptive to the charged anchor group of a polymeric dispersant.

Copper Flotation

 · Porphyry copper ores, usually medium to medium hard, require grinding to about 65-mesh to economically liberate the copper minerals from the gangue. Although a clean rougher tailing can often be achieved at 65-mesh the copper mineral is not liberated sufficiently to make a high grade copper concentrate, thus some form of regrinding is necessary on the rougher flotation copper concentrate.
